drivers/net: process the result of hdlc_open() and add call of hdlc_close() in uhdlc_close()
[ Upstream commit a59addacf899b1b21a7b7449a1c52c98704c2472 ]
Process the result of hdlc_open() and call uhdlc_close()
in case of an error. It is necessary to pass the error
code up the control flow, similar to a possible
error in request_irq().
Also add a hdlc_close() call to the uhdlc_close()
because the comment to hdlc_close() says it must be called
by the hardware driver when the HDLC device is being closed
Found by Linux Verification Center (linuxtesting.org) with SVACE.
